DESCRIPTION OF SPECIFIC ASPECTS/EMBODIMENTS

The IoT is a network of physical devices, vehicles, home appliances, and other objects embedded with electronics, software, sensors, actuators, and network connectivity which enable these objects to connect and exchange data. Each object is uniquely identifiable through its embedded computing system but is able to inter-operate within the existing Internet infrastructure.

The IoT allows objects to be sensed or controlled remotely across the network, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention. When IoT is augmented with sensors and actuators, the technology becomes an instance of the more general class of cyber-physical systems, which also encompasses technologies such as smart grids, virtual power plants, smart homes, intelligent transportation and smart cities.

IoT devices are a part of the larger concept of home automation, also known as domotics. Large smart home systems utilize a main hub or controller to provide users with a central control for all of their devices. These devices can include lighting, heating and air conditioning, media and security systems. Ease of usability is the most immediate benefit to connecting these functionalities. Long term benefits can include the ability to create a more environmentally friendly home by automating some functions such as ensuring lights and electronics are turned off.

FIG. 1 shows an example apparatus 101 comprising a processor 102, memory 103 (including computer program code) and transceiver 104 which are electrically connected to one another by a data bus 105. Furthermore, the apparatus 101 may be one or more of an electronic device, a portable electronic device, a portable telecommunications device, a mobile phone, a personal digital assistant, a tablet, a phablet, a desktop computer, a laptop computer, a server, a smartphone, a smartwatch, smart eyewear, headphones, a virtual assistant device, a router, a wireless access point, and a module for one or more of the same.

The processor 102 may be configured for general operation of the apparatus 101 by providing signalling to, and receiving signalling from, the other components to manage their operation. The memory 103 may be configured to store computer code configured to perform, control or enable operation of the apparatus 101. The memory 103 may also be configured to store settings for the other components. The processor 102 may access the memory 103 to retrieve the component settings in order to manage the operation of the other components. The transceiver 104 is configured to transmit data to, and receive data from, one or more other devices via a wired and/or wireless connection.

FIG. 2 shows one scenario to which the present apparatus may be applied. In this scenario, a first user 206 is located in a room 207 comprising a plurality of objects 208 a-d, and the apparatus (not shown) is at least part of a central device configured to communicate with the plurality of objects 208 a-d. For example, the room 207 may be the first user's living room, the plurality of objects 208 a-d may be home appliances, and the apparatus may be a virtual assistant device with a dialogue agent. The apparatus is configured to identify a target object 208 c, from the plurality of objects 208 a-d, which is within a field of view 209 of the first user 206 based on a determined location and orientation of the first user 206 relative to respective predefined locations of the plurality of objects 208 a-d.

The term ‘predefined’ is used herein to mean that the apparatus that is configured to identify the target object has access to location data which has been established for one or more of the plurality of objects. The plurality of objects 208 a-d objects may have a dynamic configuration in that one or more of the plurality of objects 208 a-d may be moved over time. If an object 208 a-d is moved, its respective location data is updated and made available to the apparatus once the location has been re-established. For example if a user chooses to relocate object 208 a, location data for object 208 may be updated either automatically if the object is configured to be connected to a central device such as server that stores the location data, or manually updated by a user inputting the new location for storage, either to the central device or the apparatus that is configured to identify the target object 208 c. Therefore even if one or more of the plurality of objects 208 a-d are moved, the respective locations remain predetermined, at least from the perspective of the apparatus configured to identify the target device 208 c.

Once the target object 208 c has been identified, the apparatus is configured to generate a command signal to trigger a corresponding action associated with the target object 208 c. The apparatus therefore allows the first user 206 to interact with the target object 208 c simply by looking at it, which facilitates management of the network.

The apparatus could be implemented in homes, offices, museums, art galleries or any other location in which one or more users 206 may be expected to interact with a plurality of objects 208 a-d. As such, the plurality of objects 208 a-d may comprise one or more of an electrical appliance, an electronic device, a portable electronic device, a portable telecommunications device, a mobile phone, a personal digital assistant, a tablet, a phablet, a desktop computer, a laptop computer, a smartphone, a virtual assistant device, a television, a monitor, a hi-fi, a loudspeaker, an artefact and a work of art (but are not limited to these examples).

The apparatus may be configured to determine the location and orientation of the first user 206 based on received location and orientation data, respectively. This location and orientation data may be received from other components of the apparatus itself, or from one or more devices external to the apparatus. For example, the location data may comprise data captured using one or more of a video camera, GPS, radar, lidar, WiFi and Bluetooth LE. Furthermore, the apparatus may be configured to identify the target object 208 c based on a determined orientation of one or more of the first user's head, body and eyes. The orientation data may therefore comprise data captured using one or more of an accelerometer, a gyroscope, a magnetometer, a compass, a head tracker and an eye tracker.

Also, the apparatus may be configured to receive the respective predefined locations of the plurality of objects 208 a-d from said objects 208 a-d. For example, each object 208 a-d may be configured to send details of its current location to the apparatus. This may occur automatically on connection of the objects 208 a-d to the apparatus and/or periodically over time to account for changes in object location. Alternatively, each object 208 a-d may be configured to send details of its current location to the apparatus in response to a request from the apparatus.

Rather than the apparatus receiving the respective predefined locations of the plurality of objects 208 a-d from the objects 208 a-d themselves, this information could be received from a central device (e.g. a server) configured to store location data for each of the plurality of objects 208 a-d. One example of this may be a server at a museum or art gallery which is configured to store location and audio data for each of the different exhibits (artefacts or works or art). Before or after the first user enters the museum or art gallery, he/she may download this location and audio data from the server (e.g. via an application or website). Once the target exhibit has been identified using the location data, the apparatus may be configured to generate a command signal which triggers the playback of audio data providing factual information about the target exhibit to the first user. This audio data may be output via a loudspeaker adjacent the target exhibit, or via an audio headset worn by the first user.

In scenarios where multiple objects 208 a-d are in close proximity to one another, there may be more than one object 208 a-d within the field of view 209 of the first user 206. In these scenarios, the apparatus may be configured to identify the target object 208 c as the object having the respective predefined location which is closest to the centre of the field of view 209. This is because the first user would typically gaze directly at the object 208 c which he/she wished to interact with.

There may also be scenarios where it is not possible for the first user 206 to interact with an object 208 a-d from any location within the vicinity of that object 208 a-d. For example, some objects 208 a-d may require the first user 206 to be within a particular distance of the object 208 a-d, or to look at the object 208 a-d from a particular position, to enable said interaction. To account for these scenarios, each object 208 a-d may have a respective interaction zone within which the first user 206 is able to interact with the object 208 a-d, and the apparatus may be configured to identify the target object 208 c further based on the determined location of the first user 206 relative to the respective interaction zones of the plurality of objects 208 a-d.

FIG. 3 a shows a scenario where there is a television 308 e within the field of view 309 of the first user 306, but the television 308 e is facing away from the first user 306 such that he/she cannot see the electronic display of the television 308 e. This situation may arise if the television 308 e was located on a table or plinth within a room 307 rather than on a wall of the room 307. Here, the television 308 e has a predefined interaction zone 310 e within which the first user 306 should be able to view the electronic display clearly (e.g. based on recommended viewing distances/angles for the television 308 e). Since the first user 306 is not currently located within the predefined interaction zone 310 e, however, the apparatus would not identify the television 308 e as the target object.

FIG. 3 b shows another scenario where there is a loudspeaker 308 f within the field of view 309 of the first user 306 but located on the other side of the room 307 from the first user 306. If the room 307 was relatively large, it may be difficult for the first user 306 to hear the audio output from the loudspeaker 308 f. As such, the loudspeaker 308 f has a predefined interaction zone 310 f within which the first user 306 should be able to hear the audio output from the loudspeaker 308 f clearly (e.g. based on recommended listening distances/angles for the loudspeaker 308 f). Since the first user 306 is not currently located within the predefined interaction zone 310 f, however, the apparatus would not identify the loudspeaker 308 f as the target object.

Depending on the particular action, the present apparatus may be configured to generate the command signal automatically on identification of the target object or in response to a user input received from the first user (e.g. a touch input, gesture and/or voice command from the first user). For example, the gaze of the first user alone may be sufficient to power-up or unlock the target object, but an additional user input may be required to activate a particular feature or obtain information. In this respect, the apparatus may comprise a list of actions for each object that can be triggered by the apparatus in response to the corresponding command signals and/or accepted user inputs. The list of actions may be predefined, for example set by manufacturer of the object, a user or an administrator. The list of actions may be updated over time to add, remove, replace, or modify one or more respective actions that can be triggered by the apparatus in response to the corresponding command signals and/or accepted user inputs.

FIG. 4 shows the triggering of an action by the target object 408 c in response to a user input. In this example, the apparatus 401 comprises one or more earbuds (e.g. an earbud in one or both ears of the first user 406), the target object 408 c is a computer, and the first user 406 has input the voice command “unlock this terminal” while pressing a button on the earbuds 401. On detection of the user input (i.e. the voice command in combination with the touch input), the earbuds 401 are configured to generate and send a command signal to the computer 408 c causing it to unlock and provide access to the first user 406. Similarly, if the target object 408 c was a hi-fi and the first user 406 was to input the voice command “play music” or similar, the earbuds 401 may be configured to generate and send a corresponding command signal which triggers the hi-fi to switch on the radio function. As another example, if the target object 408 c was a television and the first user 406 was to input the voice command “weather forecast” or similar, the earbuds 401 may be configured to generate and send a corresponding command signal which triggers the television to provide an audio and/or visual presentation of the upcoming weather predictions.

The earbuds could have built-in inertial measurement units (e.g. an accelerometer, gyroscope, magnetometer or compass) for determining the orientation of the first user's head. In this way, the earbuds 401 could provide the orientation data in addition to identifying the target object 408 c and generating the command signal. In some cases, the earbuds 401 may also have built-in position sensors (e.g. GPS, WiFi or Bluetooth LE) for determining the location of the first user 406, and may be configured to receive user inputs by incorporating a button (for detecting a touch input), capacitive sensor (for detecting a gesture) or microphone (for detecting a voice command). This would allow a single device to provide the complete functionality described herein, but could increase the size and cost of the apparatus 401. Other suitable form factors for the present apparatus 401 include a hat, headband or smart eyewear which could also incorporate the above-mentioned features.

One or both of a pair of earbuds may comprise the apparatus features as described above, namely the processor 102, memory 103, transceiver 104. Alternatively, one of a pair of earbuds may comprise some, but not all, of the apparatus features e.g. only one of the pair of earbuds may comprise transmission means while the other one does not. Any one or more earbuds comprising any suitable combination of the above apparatus features, and optionally any one or more of the built-in inertial measurement units and/or built-in position sensors, may be referred to as a “smart” earbud (or earbuds).

In the example of FIG. 4 , a second user 411 is in proximity to the first user 406 as the first user 406 provides the user input. As such, the second user 411 may be able to access the target object 408 c when it is unlocked to the first user 406. This may be beneficial if the first user 406 wishes to share information on the target object 408 c with the second user 411 or demonstrate a feature of the target object 408 c to the second user 411. The apparatus 401 may also be configured to determine the location and orientation of the second user 411 (as described above in relation to the first user 406) to determine if the second user 411 is currently gazing at the target object 408 c of the first user 406. In this example, the apparatus further comprises one or more earbuds 401′ worn by the second user 411 for determining the location and orientation of the second user 411. If the apparatus 401 determines that the second user 411 is currently gazing at the target object 408 c, the generated command signal may be configured to trigger the sending of a text message or email from the first user 406 to the second user 411 on receipt of a corresponding user input (e.g. “send this” voice command or similar).

In some cases, the generated command signal may be configured to cause the target object 408 c to allow one or more further users to interact with the target object 408 c according to respective permissions allocated to the one or more further users by the first user 406 or the apparatus 401. The respective permissions may comprise access rights with or without corresponding time constraints, which may be useful for hot-desking situations in an office. In the scenario of FIG. 4 , for instance, the command signal generated by the apparatus 401 may be configured to unlock the target object 408 c for a predefined time period to provide access to the second user 411 as well as the first user 406 during this time period.

In cases where the respective permissions are allocated to the one or more further users by the apparatus 401 itself, these may be based on at least one of the proximity of the further users to the first user 406, their location and orientation relative to the location of the target object 408 c, and their relationship with the first user 406 (e.g. from stored relationship information about the users). For example, the proximity of the second user 411 to the first user 406 in FIG. 4 may indicate a working relationship between the first 406 and second 411 users which requires both users 406, 411 to have at least partial access to the target object 408 c.

There may be situations where a further user should not have access to the target object 408 c of the first user 406, however. For instance, the first user 406 may wish to view his/her bank account information on an electronic display without anyone else being able to see this information. To address this issue, the apparatus 401 may be configured to request approval from the first user 406 of the permissions allocated by the apparatus 401. Additionally or alternatively, the apparatus 401 may be configured to identify the one or more further users (e.g. based on location data captured using a video camera or a user input captured using voice-recognition software), and store the identities of the one or more further users together with their respective permissions and/or interactions with the target object 408 c. The interactions of the further users with the target object 408 c may include use of the target object 408 c by the further users, or the granting of access by these further users to additional users. In some cases, the apparatus 401 may be configured to output the identities of the identified further users together with their respective permissions and/or interactions with the target object 408 c, or send the same to another device associated with the first user 406 (e.g. smartphone, tablet or laptop) for output. The information may be output to the user by a combination of the apparatus 401 and a user device (e.g. earbuds 401 provide audio output and a paired smartphone provides visual output).

These security features may help to prevent accidental or malicious access to the target object 408 c, which may be useful when the first user 406 is unaware of the proximity of a further user. In the banking scenario described above, the first user 406 may react to the information sent by the apparatus 401 by shielding the electronic display or logging out of his/her bank account to prevent the account information from being seen by the further user. In some cases, the first user 406 may decline or remove the permissions allocated to the further user.

The above-mentioned security features may only be activated when the apparatus 401 is unsure about whether a further user should have access to the target object 408 c of the first user 406 or not. For example, the apparatus 401 may be configured to calculate a confidence score for each of the further users (e.g. based on at least one of the proximity of the further users to the first user 406, their location and orientation relative to the location of the target object 408 c, and their relationship with the first user 406) and activate the security features if the calculated confidence score falls within a predefined range of confidence (i.e. neither high nor low).

Instead of a single apparatus configured to both identify the target object and generate the command signal to trigger a corresponding action associated with the target object, this functionality may be distributed between multiple apparatuses (not shown). For example, a first apparatus (e.g. a low powered device such as a pair of earbuds) may be configured to send a request to identify the target object to a second apparatus (e.g. a more powerful device such as a smartphone, tablet PC, server or home hub). In this example, the second apparatus then identifies the target object (assuming it has access to the relevant location and orientation data) and either generates the command signal itself, or transmits a message comprising the identity of the target object to the first apparatus and/or a further apparatus (e.g. another device specified by the user such as a smartphone, tablet, PC, server or home hub) such that the first apparatus and/or further apparatus can generate the command signal. In some cases, the first apparatus may provide the location and orientation data to the second apparatus together with the request.

Distributing the functionality between multiple apparatuses may be useful when the processing power of the first apparatus is insufficient for identifying the target object or is relatively limited in comparison to the second apparatus, as the more demanding step is offloaded from the first apparatus to the second apparatus.

FIG. 5 shows the main steps 512-513 of the method described herein. The method generally comprises: identifying a target object, from a plurality of objects, which is within a field of view of a first user based on a determined location and orientation of the first user relative to respective predefined locations of the plurality of objects 512; and generating a command signal configured to trigger a corresponding action associated with the target object 513.

FIG. 6 shows a computer/processor readable medium 614 providing a computer program. The computer program may comprise computer code configured to perform, control or enable one or more of the method steps 512-513 of FIG. 5 using at least part of the apparatus described herein. In this example, the computer/processor readable medium 614 is a disc such as a digital versatile disc (DVD) or a compact disc (CD). In other embodiments, the computer/processor readable medium 614 may be any medium that has been programmed in such a way as to carry out an inventive function. The computer/processor readable medium 614 may be a removable memory device such as a memory stick or memory card (SD, mini SD, micro SD or nano SD).
